That's how I learned. Error after error. To be honest with ya. In my mind I have never had a perfect screen. Maybe that's why I keep going back to it. In that regard, those error's made me focus on the wonderful world of horticultural science. I have a solid background working around Horticulturalists my whole life. But shit once you have the drive to learn it for yourself, the gloves come off!! Anyway i hope you give it another go and if ya need any help PM me and I'll do what i can from this keyboard to help ya haha
